> When binding builder with multiple topics, single resultant topic has

> This issue is at millisecond level. When messages with same milisecond level
> are added in topics.
> Scenario : (1 producer : p1 , 2 topics t1 and t2, streams pick form these 2
> topics and save in resulting t3 topic, 4 partitions of t3 and 4 consumers of
> 4 partitions )
> Case: When p1 adds messages with same millisecond timestamp into t1 and t2 .
> Stream combine and form t3. When this t3 is consumed by consumer, it has
> different order of same millisecond messages.
